Choose the correct description for each "Law" of Electricity & Magnetism.
The choices are
faradays law
lenz law
ampere law
are my choices correct
Gives the amount of current resulting from a changing magnetic field.AMPERE
LAW
Gives the strength of the magnetic field resulting from the current in a wire.FARADAYS LAW
Both are wrong.
You mixed up the definitions of Faraday's and Ampere's Laws.
For Lenz's Law, see

No, your choices are not correct. Let me explain the correct descriptions for each of the laws you mentioned:
1. Faraday's Law: Faraday's law of electromagnetic induction states that a change in the magnetic field within a closed loop of wire induces an electromotive force (EMF) in the wire, which results in the generation of an electric current. It explains the relationship between changing magnetic fields and the production of electric currents.
2. Lenz's Law: Lenz's law is a consequence of Faraday's law and is used to determine the direction of the induced current. Lenz's law states that the direction of the induced current in a closed loop is such that it opposes the change in magnetic field that produced it.
3. Ampere's Law: Ampere's law relates the magnetic field produced by a current-carrying wire to the current passing through the wire. It states that the magnetic field around a closed loop is directly proportional to the current passing through the loop. Ampere's law allows us to calculate the magnetic field around current-carrying wires or in certain symmetrical situations.
Now, let me provide the correct description for each law based on your choices:
Gives the amount of current resulting from a changing magnetic field: This description matches Faraday's Law of electromagnetic induction.
Gives the strength of the magnetic field resulting from the current in a wire: This description matches Ampere's Law.
Therefore, the correct choices are:
- Faraday's Law: Gives the amount of current resulting from a changing magnetic field.
- Ampere's Law: Gives the strength of the magnetic field resulting from the current in a wire.
Lenz's Law was not one of the options you provided.
